EBERHARD KLEPPER, OF CRMMITSCHAU, GERMANY.

APPARATUS FOR ERGDUCING CRINKLED PAPER.

Application filed December 10, 1923. Serial No. 679,789.

To all whom t may 'concern' Be it known that I. Ennnimno Knnrricn, a citizen of the Republic of Germany, residing at Crimmitschau, Saxony, Germany, have invented certain new and useful Iniprovements in Apparatus for Producing Crinkled Paper, of which the following is a specification. Y

My invention relates to apparatus for producing a paper having a veined or crinkled appearance, suitable 'for use as a wall paper, and for other purposes.

An important object of the invention is to provide an apparatus ofthe above mentioned character, so constructed that a veined or crinkled paper may be produced cheaply and quickly. V l l A further object of the invention is to provide means for treating the paper after being subjected to the heating and drying action, for restoring its original lustre and appearance.

Other objects and advantages of the invention willvbe apparent during the course of the following description.

l In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a central vertical longitudinal section through an apparatus employed in the practice of my method,

Figure 2 isa plan view of a section of the completed product, and,

Figure 3 is' a detail section through the same.

. In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a supporting frame, embodying a table 6.

Arranged at one end of the frame 5, near its. lower end, is a cylinder 7, carrying a roll 8 of a backing sheet or strip, such as a suitably heavy paper or fabric. The cylinder 7 is detachably rotatably mounted upon arms or brackets 9, secured to the frame. The heavy backing sheet 'from the roll 8, designated 8, passes over the table top 6 and.1 travels longitudinally thereof to the rig t.

The frame 5 is provided near its top and at its left end with arms 10, detachably and `rotatably supporting a cylinder 11, which carries the roll 12 of the rumpled or crinkled paper, such as tlssue paper. Now 'this paper may be rumpled or crinkled before being wound upon the cylinder 11, and it should not be drawn too tightly so that the crinkles or rumples would he smoothed out, as the paper must be fed in the crinkled or rumpled condition to the upper surface of the backing sheet 8,. The crinkled paper 12', from the roll 12, first passes over an upper table 13, and then down aboutvertical rollers 14:, and continues in a horizontal direction lin contact with the backing sheet 8', about a roller 15,-as shown.

lrrrranged in the upper portion of the frame 5, near its left end, is a tank or receptacle 16, for holding the sizing or paste,

which is in a suitablyscmi-luid condition, wherebj,7 it may be discharged vin a substantially uniform manner to the upper surface of the backing sheet 8.. This sizing or of thetank 16, which may be provided with apertures of suitable iineness at its bottom. The bottoin-17 extends for substantially the entire width'of the backing sheet 8', as is obvious. Supported in advance of the bottoni 'or outlet 17 is a brush 18, which ap plies the sizing or paste evenly to the surface of the backing sheet 8. This backing sheet is relatively stout or heavy and free from c-riukles. It is ,thus seen that this surface of the backing sheet, with the sizing or paste thereon, and while wet, refeives the crinkled or'wrinkled upper sheet or tissue paper 12. lThese two layers of paper then discharge .from the roller 15, and are sub-l jected to a suitable compression and heat, 'in a closed receptacle or chamber. Prior to the"passage to the roller 15, the upper and lower sheets, while cemented together, and damp or wet, travel over a trough 15', supported beneath the table 6. This trough projects beyond 'the edges of the table and holds aniline dye, which may be applied by hand to the upper surface of the damp c rinkled paper.

This heating means embodies a chamber paste is discharged from the lower end 17 19, in which-.are three vsuitably ,supported rollers or cylinders 20, 21 and-22. These cylinders 20 and 22 are preferably in the same 'horizontal plane, while the cylinder 21 is in a higher plane. The cylinders are covered with an asbestos sheet or facing 23, and

a cover 24 of linen or other fabric so that the paper will not stick to the metal wall of the cylinder, or burn. The cylinders are equipped with electrical heating means, such i as resistance coils 23, arranged therein. It

. 90 C. The paper embodying the upper and l lower sheets is passed beneath the cylinder 20, above the cylinder 21, and then beneath the cylinder 22., These cylinders are freto rotate and are turned by the pull upon the paper.

The paper passing from the chamber 19 next discharges into a closed chamber 24, in which are mounted rollers 25, at different elevations, so that the paper is made to.

travel inl a plurality of runs `through the same. The paper is drawn through the chamber 24 by passingabout a cylinder or roller 26`- and being wound upon a cylinder 27, which m'ay be turned by a. crank 28. It might be stated at this point that the invention is in no sense restricted to this method of advancing the paper, although it is believed to be satisfactory. rIhe drying cylinders might be mechanically driven, if desired. Also the cylinder 11 carrying thel crinkled or rumpled paper may be turned by hand, to relieve this paper of any strain, which would tend to uncrinkle the paper, or it might be mechanically driven. However, this roll of paper is light and will turn freely, and 'it is ordinarily not necessary to drive the same. When the paper passes from the heating rolls, it may be found that it has lost some of its healthy fresh appearance, or lustre, and I have found that this may be restored within the chamber 24 by circulating moist cold air in contact therewith. This is elected b means of a blower A29, the air discharging t rough the lo utet 30.

In theuse of the ap aratus in the practice of my method, the bac ing sheet 8 is caused to travel longitudinally upon the table 6, and the upper crinkled sheet l2 is caused to travel longitudinally and is brought upon the upper surface of the backing sheet which is coated -with the sizing orpaste. These two sheets thussecured together are passed between the heating cylinders, and there -as the means for effecting the longitudinal subjected to pressure/and a'l gradually in- 50 creasing heat, as they pass from one cylinder to the-ether. By the time the material discharges from the last cylinder 23, possessing the maximum heat, it is dry and thenf discharges into the chamber 24, wherein it is subjected to the action'of moist cold air, which restores the fresh healthy appearance or lustre to the paper. The product is then wound upon the cylinder 27, which is shown travel of the paper. The paper is ordinarily made with a margin at the edges, which must be cut oi", and I also contemplate winding the paper from the cylinder 27 land rewinding the samecin rolls of desired length, ready for being placed u on the market.

It is to be understoo that the form of my invention herewith shown and described isl to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts 0f. the apparatus may be resorted to, and also that changes may be made in the steps of the method, and their order, without departing from the s irit of my invention or the scope of the subgoined claim.

Having thus described my invention, I v claim:

Apparatus for producing a crinkled paper, comprising a table, a sup ort for the table, means for supporting a rol of backing paper near one end of the table to deliver the same to the u per surface of the table, a tank arran ed a ove the table for feeding a sizing to t e upper surface of the paper, means for supporting a roll of erinkled paper in a manner to delivervthe same to the upper coated face of the backing paper, a heating chamber, a plurality of heated cylinders mounted Withln the chamber about which the paper travels, a restoring chamber having means therein for supporting the paper in a plurality of runs, and means for effecting a'circulation of fresh cold air within the restoring chamber. v

In testimony whereofI ailx my signature.
